■“Units”
The units of measurement used fo r the speedometer, odometer, and
trip information can be changed.
Each time right on the control pad
is pressed, the distance (miles,
km), the speed (MPH, km/h) and
the fuel consumption (MPG, km/l,
L/100km) measurement units will
be changed.
■ “Temp” (temperature)
The units of measurement used fo r the outside temperature, engine
coolant temperature, engine oil temperature and air conditioning tem-
perature displays can be changed.
Each time right on the control pad
is pressed, the temperature display
unit will be changed (Fahrenheit,
Celsius).

■Meter operation restrictions while vehicle is in motion
While the vehicle is in motion, some menu items cannot be changed using the con-
trol pad. Restricted items are displayed in gray or without an arrow. These items can
be operated once the vehicle is stopped.
■“Rev Ind” (rev indicator)
●Even if the green or amber indicator is set to 9000 rpm, the over-rev warning
will be displayed.
●If the green and amber indicators are both set to the same engine speed, the
indicator will be shown in amber.
■Measuring the engine oil level
●The dry sump lubrication system circulates the engine oil between the engine
and oil tank according to driving conditions. Accordingly, the engine oil level in
the oil tank may vary even if the overall amount is constant, affecting the mea-
surement results.
●It takes some time for the engine oil level to stabilize after the engine is started.
To obtain a more stable result, drive the vehicle for a while and then perform the
measurement without stopping the engine.
●If an attempt to measure the oil level is made immediately after the previous oil
level measurement process was completed, the previous measurement may be
displayed.
●If the measurement result flashes, the measuring function is malfunctioning.
Have the vehicle inspected by your Lexus dealer.
■Engine oil maintenance
“Oil maintenance required” will be displayed once the vehicle has been driven for
more than 6214 miles (10000 km) since the last reset. (
P. 3 2 7 )
The engine oil may need to be replaced earlier depending on driving conditions.
●Over-rev warning (regular setting)
If the engine speed enters the red zone, the
over-rev warning will be shown in red
regardless of the set speed.

When driving
■Tire grip at low temperatures
The tires fitted to the LFA are designed for dry road conditions. As such, tire grip on
cold, snowy and/or icy roads will be reduced compared to standard tires.
Be sure to use snow tires on snowy and/or icy roads and drive carefully at a speed
appropriate for road and weather conditions.
■Engine starting restrictions
In order to protect the engine, the engine may not start when the engine coolant
temperature or engine oil temperature is below -13 F (-25C). In that case, a
buzzer will sound and “Temp low Engine cannot be started” will be shown on the
meter. ( P. 3 2 7 )
CAUTION
■Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in a loss of vehicle control and cause death or serious
injury.
●Use tires of the specified size.
●Maintain the recommended level of air pressure.
●Do not drive in excess of 75 mph (120 km/h), regardless of the type of snow tires
being used.
●Use snow tires on all, not just some wheels.
NOTICE
■Driving with tire chains
Do not fit tire chains. Tire chains may da mage the vehicle body and suspension, and
adversely affect driving performance.
■Repairing or replacing snow tires
Request repairs or replacement of snow ti res from Lexus dealers or legitimate tire
retailers.
This is because the removal and attachment of snow tires affects the operation of
the tire pressure warning valves and transmitters.

Maintenance and care
NOTICE
■Application of coatings to the vehicle body
Do not apply any kind of coating to the vehicle body as doing so may damage the
paint or reduce its durability.
■To prevent paint deterioration and corrosion on the body and components (alu-
minum wheels etc.)
Observe the following precautions:
●Wash the vehicle immediately in the following cases:
• After driving near the sea coast
• After driving on salted roads
• If coal tar or tree sap is present on the paint surface
• If dead insects, insect droppings or bird droppings are present on the paint
surface
• After driving in an area contaminated with soot, oily smoke, mine dust, iron
powder or chemical substances
• If the vehicle becomes heavily soiled with dust or mud
• If liquids such as benzene and gasoline are spilled on the paint surface
●If the paint is chipped or scratched, have it repaired immediately.
●To prevent the wheels from corroding, remove any dirt and store in a place with
low humidity when storing the wheels.
For the Matte Black, pay attent ion to the following as well:
●If anything is spilled on a painted surface, wipe it off as soon as possible.
If spilled washer fluid or alkaline fluids are left as is, the paint in the affected area
may deteriorate, causing blemishing.
●Do not wax or apply coating to the vehicle.
Doing so may cause a change in the body surface's texture or irregularities in the
paint.

Maintenance and care
CAUTION
■If your vehicle is not properly maintained
Improper maintenance could result in serious damage to the vehicle and possible
serious injury or death.
■Handling of the battery
●Engine exhaust, some of its constituents, and a wide variety of automobile com-
ponents contain or emit chemicals known to the State of California to cause can-
cer and birth defects and other reproductive harm. Work in a well ventilated area.
●Oils, fuels and fluids contained in vehicles as well as waste produced by compo-
nent wear contain or emit chemicals known to the State of California to cause
cancer and birth defects or other reproductive harm. Avoid exposure and wash
any affected area immediately.
●Battery posts, terminals and related accessories contain lead and lead com-
pounds which are known to cause brai n damage. Wash your hands after han-
dling. ( P. 2 6 5 )

Maintenance and care
CAUTION
The engine compartment contains many mechanisms and fluids that may move sud-
denly, become hot, or become electrically energized. To avoid death or serious injury,
observe the following precautions:
■When working on the engine compartment
●Keep hands, clothing, and tools away from the moving fan and engine drive belt.
●Be careful not to touch the engine, exhaust manifold, etc. right after driving as
they may be hot. Oil and other fluids may also be hot.
●Do not leave anything that may burn easily, such as paper or rags, in the engine
compartment.
●Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes are flam-
mable.
■When working near the electric cooling fan
Be sure the ignition switch is in the “LOCK” position.
With the ignition on, the electric cooling fan may automatically start to run if the air
conditioning is on. ( P. 2 6 1 )
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from getting
in the eyes.
NOTICE
■If you remove the air cleaner filters
Driving with the air cleaner filters remo ved may cause excessive engine wear due
to dirt in the air. Also a backfire could cause a fire in the engine compartment.
